Heat index values are of high significance for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
